General Description
The AT1393 provides a complete power solution
for digital still and video cameras through the
integration of synchronous rectification topology ,
soft start function and short circuit detection
function. This IC is ideal for applications that use
either 2 or 3 alkaline or NIMH batteries as well as
those using a single Li-ion battery.
Applications
• Digital Cameras
• CCD Imaging Devices
• Camcorders
